Abstract
A method for making tip filter includes such technological steps as adding chitosan (0.01-3 kg) to 4% aqueous solution of acetic acid (5 kg), stirring while dissolving, addition of powdered activated carbon (0.01-3 kg), stirring, addition of fibrous filler, stirring, shaping and drying, and features use of the disolubility, adsorptivity and porosity of chitosan and the dual adsorption of chistosan and activated carbon. Said tip filter has high adsorption effect.
Description
The present invention relates to method for producing filter tip.
The cigarette filter of present domestic employing does not contain active material, therefore, the nicotine that produces in the smoking process, harmful material such as tar, a part directly enters human body, and human body is damaged, and another part enters air, and air is polluted.So abroad some cigarette factories add granular activated carbon in filter tip, in order to the part harmful substance that is produced in the absorption smoking process, but under these process conditions, the active carbon specific area is little, skewness, and adsorption effect is undesirable.
The invention provides that a kind of technology is simple, the filter production method of advantages of good adsorption effect.
The present invention adopts following measures in order to achieve the above object: method for producing filter tip is to add 0.01～3kg to go acetyl chitin stirring and dissolving in 5kg 4% aqueous acetic acid, adding 0.01～3kg Powdered Activated Carbon stirs, add 1～3kg fiber inserts again and stir, shaping, dry getting final product.
The present invention utilizes solubility, adsorptivity, the porous characteristics of shitosan (deacetylate chitin); the mixed inserts that adds of it and powdered active carbon is shaped and makes; utilize the dual absorption of shitosan and active carbon; simultaneously; shitosan be water-soluble after; again with active carbon; the fiber inserts is mixed evenly to be made; therefore, be evenly distributed, the powdered active carbon specific area is big; advantages of good adsorption effect; the harmful substance that can adsorb in the smoking process effectively to be produced had both protected the smoker healthy, prevented air pollution again.
Elaborate below in conjunction with embodiment.
Embodiment 1;
In 5kg 4% aqueous acetic acid, add 3kg deacetylate chitin stirring and dissolving, add the 3kg Powdered Activated Carbon and stir, add 3kg fiber inserts again and stir, shaping, dry getting final product.

In 5kg 4% aqueous acetic acid, add 0.5kg deacetylate chitin stirring and dissolving, add the 0.5kg Powdered Activated Carbon and stir, add 2kg fiber inserts again and stir, shaping, dry getting final product.
Embodiment 3;
In 5kg 4% aqueous acetic acid, add 3kg deacetylate chitin stirring and dissolving, add 0.01kg deacetylate chitin stirring and dissolving, add the 0.01kg Powdered Activated Carbon and stir, add 1kg fiber inserts again and stir, shaping, dry getting final product.
